Oh OP, If there really is no way you can avoid doing this, it really would be best to invest your energy and efforts into how you ‘can’ do this, rather than ‘you can’t’. To help you feel prepared for this.
Some things you can do:
Instead of thinking of all of those people, imagine you will be sharing your information with a couple of colleagues or friends who you feel relaxed with. In your practicing, and for the real thing, address your friends/colleagues. Make yourself do this to help yourself.
Remember - most of, if not all, the audience listening will be wanting to hear your presentation. Most people are kind and understanding. In your preparation, see that kind and understanding group rather than a bunch of ogres.
Are you passionate about what you have to present? Let that come across, tap into who you are naturally rather than trying to force something/be someone who you’re not. Your natural interest and enthusiasm will shine through; because you will be speaking of things you ARE good at and interested in.
Start preparing your presentation now, so that you are fully au fait with the content, how it flows, etc.
Could the presentation be broken into 3 chunks?
Use slides/pictures to inform your speaking. People like and appreciate visuals.
In your mind, you will know know you have completed section 1, just 2 to go, for example.
3 sections taking 3 minutes each = done. Ha - and you’re delivering for 9 minutes, not 10!
Turn all of your ‘I can’ts’ into ‘I can, I am, I will...’. Because you can. And you will. This really will give you a better experience and outcome.
Breathe...keep your shoulders dropped and relaxed, keep your jaw relaxed and loose...
You can do this. You will kill it.
